66 Suburban questions

[2tontruck]

Ok, So our company just bought a 66 Suburban and we are looking for a hard to find items. It seems that the third row seat seems to be impossible to find as well as the weatherstrip that goes around the clam shell doors in the rear. Does anybody have any reccomendations for us? We would really like to find these items to finish it off but I have looked and just cant seem to find anything. Any help would be great. Thanks, 2tontruck!
